The tree appears to be a Shumard oak (Quercus shumardii) or a very close relative in the red oak group.  The issues in your images are absolutely not oak wilt.  You have some minor leaf spotting caused by one of the common fungal leaf spot pathogens, some feeding by a caterpillar, and symptoms of iron chlorosis where the veins on the leaves are dark green on a chlorotic (yellow) background.  None of these issues pose any major health threats to the tree.  The iron chlorosis could be a symptom of overwatering your lawn (red oaks hate "wet feet"), disturbed soils, fill soil, or some other cause of root dysfunction.  Some red oaks are genetically disposed to iron chlorosis.  The problem can be corrected with supplemental micronutrients, but will probably return and be a reoccurring symptom on the tree.

Hello David,

Very best,
